Sometimes I Get Stronger From The Sun

I can help you have some fun,
Sometimes I get stronger from the sun,
If you never give me a break,
You will find I never wake,
I am optimistic on one side,
I can be short, fat, tall or wide,
Rectangle and cylinder are two of my shapes,
And I can even help you make video tapes,
Sometimes you must wait for me to get ready,
Just hold on for a few hours and be steady,
I can help you get around the mall,
Or help you make a telephone call.

What am I?

A battery. Games and other entertainment devices run on batteries. Batteries can be charged using solar power, which is from the sun. If you use a battery-powered device long enough, the battery will die. Batteries have a plus side and can be all shapes and sizes. They can power scooters and Segways commonly used in malls and your cell phone requires a battery to function.
